As the title implies, this is the 4th instalment in Rocket Recordings‘ sold-out split series, to which their page attests;

“The Rocket Recordings Collisions series has thus far seen luminaries like The Heads, White Hills, Oneida, Mugstar, Shit & Shine and Gnod locking horns against each other on psychic voyages to bold dimensions anew. The latest instalment again deals with a pair of hand-picked, boundary-breaking iconoclasts, pushing the Collisions series further out into the realm of the unexpected, as this Anglo-Italian pair of perversely kindred spirits combine to wreak havoc.”
